Sub-address Field and Default Sub-address
The second field in an ISiCL command line is the card address, or “sub-address” field. This field
identifies specific common and channel modules within a given ACS-160 Series multiplexer. Table
5-4 shows valid ACS-160 Series multiplexer sub-addresses.
In a drop and insert multiplexer, only the DI-A module accepts and processes commands targeted
for channel modules, commands with a sub-address of the form Cn where n is a number from 1 to
36. Therefore, when using either a local controller or a remote controller to perform channel
module operations on a drop and insert multiplexer, always establish the connection through the
remote port on the DI-A module. In the case where both CM-5RB modules of a drop and insert
multiplexer are connected to a controller via a data network, commands issued with the proper
multiplexer address and channel module sub-address are automatically processed by the
multiplexer’s DI-A module and ignored by its DI-B module.
In an ACS-166 dual terminal multiplexer, each of the two CM-5RB modules accepts and processes
commands for its associated channel module. Each CM-5RB module must be given a different
network address if the multiplexer is connected to a data network controller.
If the sub-address field is left blank, the default sub-address is TERM. This feature is convenient
for addressing the CM-5RB module in a terminal multiplexer. The default cannot be used with a
drop and insert multiplexer. When using the default, the colon terminating the sub-address field
must still be present. For example, this command uses the default sub-address to send a
configuration inquiry to a terminal multiplexer:
::CONFIG?:;
Table 5-4. Sub-address Field Entries
Sub-address Description
TERM Use this sub-address in commands issued to the CM-5RB module in a terminal multiplexer.
In an ACS-166 dual terminal multiplexer, both CM-5RB modules have the sub-address
TERM. Use the multiplexer address to differentiate between them if they are both
connected to the same network controller.
DI-A Use this sub-address in commands issued to the CM-5RB module configured to operate in
the DI-A mode in drop and insert multiplexers.
DI-B Use this sub-address in commands issued to the CM-5RB module configured to operate in
the DI-B mode in drop and insert multiplexers.
Cn
(n = 1, 2,...36) Use this sub-address format in commands sent to remotely controllable channel modules.
Note that n is the sub-address number or “card address” of the target channel module
within the multiplexer. This sub-address should not be confused with the multiplexer’s
network address.
Channel module addresses are set using switches on the channel modules themselves. The
card address is generally set to the same number as the physical slot the module occupies,
or, in an expansion shelf, to that number plus 18. This convention is not required, but it
makes for easier maintenance.
Each channel module within a given multiplexer must, of course, be assigned a different
number. Valid channel module numbers are the integers from 1 to 36.
The individual channel module manuals give details on setting the card address.
For terminal multiplexers using redundant CM-5RB modules, the primary CM-5RB module is
accessed using the ISiCL sub-address TERM, and the backup is accessed using the ISiCL sub-
address BTERM. In a drop and insert multiplexer, only the DI-A module accepts and processes
commands targeted for channel modules (that is, commands with a sub-address of the form Cn,
where n is a number from 1 to 36). Therefore, when using either a local controller or a remote
controller to perform channel module operations on a drop and insert multiplexer, always establish
the connection through the remote port on the DI-A module. In the case where both CM-5B
modules of a drop and insert multiplexer are connected to a controller via a data network, the
multiplexer’s DI-A module automatically processes commands issued with the proper multiplexer
address and channel module sub-address, and the DI-B module ignores the commands.
